FLUID-MIXING FIXTURE.

SPECIFICATION forming part of Letters Patent No. 659,260, dated October9, 1900.

' Appnmion tied May 3, 1900. serial No. 15,324. (No man.)

To a/ZZ whom it may concern:

Be it known .that I, ALFRED A. SCHRATZ, a citizen of' the United States,residing` at Detroit, county of Wayne, State of Michigan, have inventeda certain new and useful Improvement in Fluid-Mixing Fixtures; and Ideclare the following to be a full, clear, and exact description of thesame, suchas will enable others skilled in the art to which it pertainsto make and use the same, reference being had to the accompanyingdrawings, which form a part of this specification.

This invention relates to a fixture for mixing a disinfecting iiuid withwater, and has for its object an improved fixture intended to be used inplaces where itis desired to employ an antseptic wash-water; and thepurpose of the invention is to produce a fixture which will mingle anantiseptic iiuid with a stream of water iiowing from any source ofsupply.

In 'the drawings, Figure l is a vertical elevation, partly in section.Fig. 2 is a drawing, most-ly in section, and shows the parts as theyappear on a plane passing diametrically and vertically through thefixture and at right angles to the plane ofthe section shown in Fig. l.

1 indicates the stem, which is arranged to be secured to afable-top by aspindle la, screwthreaded at its end, adapted to be passed through thetable-top and to have a nut lb run onto the threaded part of thespindle. The fixture is provided with a chamber 2, into which leadwater-pipes 2iL and 2b, one ofthe inleading water-pipes being intendedfor warm water and the other for cold water, each leading from anindependent source of' supply, as from a water-main and a boiler. Eachwater-main is provided with its individual cutoff valve 2C and 2d. Fromthe bottomv of the chamber a passage 2e leads out to a faucet 2f. Fromthe upper end of the chamber 2 a passage 2g leads upward to a valve 3.Between the outlet 2g and the valve 3 there is a checkvalve 3, seatingdownward and adapted to be opened by the fiow of liquid from the chamber2. Above the check-valve 3a is an adjusting-nozzle 3b, which limits theopening movement of the check-valve and which may be adjusted bychanging its vertical position with reference to the check-valve. Theadjustment is effected by making the nozzle as a screw-nipple andengaging it in the hollow screw 3C, which forms the upper part of thefixture just below the casing of the valve 3. A valve-casing 4 islocated just above the parts previously described and is fitted with athree-way plug-valve 3. The passage leading from the chamber 2 leadsinto the chamber of the valve-casing 4, and a second passage 4 leadsvertically downward into the same chamber from a higher part of thefixture. On the upperend of the fixture is mounted a tank 5, the outletof which is engaged in the fixture and the passage through the outlet ofwhich c'ommunicates with the passage 4a, and through the passage 4a itcommunicates with a passage 3d in the plug-valve. In the passage 4a,between the tank and the upper portion of the casing 4, is insertedapressure-reducing nipple 6, which is removable from the fixture. Thenipple 6 is provided with a flange 6a, that rests on an annular shoulder4b in the fixture. The nipple is provided with a hollow stem-likeprojection perforated with small holes 6b, which constitutecommunicating passages through the nipples between the tank and thecasting, and a nipple with holes of proper size with reference to thehead of the water and with reference to the size of the tank 5 mayalways be used--as, for example, if the tank 5 be large, so that therewill be a considerable head of liquid in it, a nipple with smallperforations 6b may be selected and the outflow of liquid limited, andthis limitation may be made with reference tothe normal flow of waterthrough the pipes 2a and 2. Such regulation need only be made once forthe same instrument, and it is consequently not necessary to make thispart adjustable, as the single adjustment of the nozzle 3b will sufficeto regulate with sufficient accuracy the mingling of the water with theantiseptic. The plug-valve 3 is turned by a handle 7 to bring thepassage 3e and the passage 3d into position to permit the iiow of waterfrom the passage 2g through the passage 3e to the outflownozzle 8 and atthe same time to permit the flow of the antiseptic liquid through thepassage Sd into the passage 3e. When thus arranged, the mingling waterand antiseptic are delivered from the nozzle 8. Clearwater may be drawnfrom the nozzle 2f. Generally when clear Water is drawn the valve 3 isturned to prevent the passage through it of either water or antiseptic;but even if it be not turned the check-valve 3 prevents the` return flowof water through vthe passage 21W and prevents the entrance of anyantiseptic into the chamber 2.

What I claim is- 1. In a xturefor mingling antisepticfluid With water,in combination with a standard provided with an i'nfio'W-pipe -for waterand a nozzle for the. delivery of ythe-same, an afntii septic-tankconnected with the fixture, a three-way valve adapted to allow the fiowtherethrough of both Water and the antiseptic liquid, a nozzle for thedelivery of the Vln-ingled liquids, and a check-valve in the xture.between the inow-pipe for water and the the inflow-'pipe for water, andthe three-way valve, and a regulating-nipple adjustable with respect tothecheck-valve, and adapted to determine the amount to which thecheckvaflve opens, substantially as described.

In testimony whereof I sign this specification in the presence of twoWitnesses.
